BRASSERT @a l COMPANY, OF CHICAGO, ILLINOIS,ACORPORATION OF ILLINOIS n CHECKER CONSTRUCTION Application led February9, 1931. Serial No. 514,438.

This invention relates to improvements in the checker construction inregenerators for use in hot blast stoves, open hearths, soaking pits o-rheatingk furnaces and to the regenerativeV systems. This inventionparticularly applies to the construction of regener-v ators in whichsmaller areas of openings are used at the bottom than at the top, whichrenders diicult the problem of supporting the checker column at thebottom due to the smallness of the openings and the intervening walls.The checker column is built up out of tile or individual brick.

rIhe bottom support consists of metallic 4elements which correspond inthickness to the filler brick above and are designed in that fashion inorder not to obstruct the checker openings. The employment of thesesupports necessitates building up the walls in between them of smallmitre shape b-rick which are objectionable on account of their smallsize and number of joints, which cause them to become loose and dropout. In order to do away with these joints and still permit the use ofmetal supports under the filler brick, I propose to use a brick in theform of a cross made of one piece, either of brick or of metal whichwill replace the four mitre brick used at present. Or I propose to use abrick or metal tile containing a number of openings tallying with thechecker openings and fitting in with the metal supports of the fillers,or the metal support may be cast integral with this brick or metalsupport.

It is therefore an object of my invention to construct the supportingmembers for the checker brick and filler brick in substantially H-shapedform and of similar dimensions, whereby the cross bar of' the supportingmember serves to support the filler brick and the ends or sides supportthe checker brick.

It is a further object of my invention to so design the supportingmembers that the outside contour will conform to the contour of thechecker brick supported thereabove, whereby each checker brick restsupon parts of five adjoining supporting members.

Further objects and advantages of my in- Yvention will be more readilyapparent and better understood from the vfollowing detailed descriptiontaken in connection with the attached drawing, in `which different formsof construction are illustrated.

In the drawing- Figure 1 is a plan View showing the manner ofassociating and positioning a plurality of supporting members. y

Describing first the form of my invention'.

illustrated in Figuresl to 5, inclusive, it will be understood thatvertical columns of checker brick 10 which may bein the form shownofvoctagonal section, are generally carried directly by the rider tilemembersV 11, if ller brick are not employed.. However, iffiller brickare loosely inserted in the vertical flow passages in 'and between thesechecker brick, itis necessary to employ some form 'of Ysupporting Vmeanstherefor.

Previous arrangements employing metal bars have been undesirablesincesmall pieces ofbrick are required to fill up the spaces and are liableto drop outof pla-ce. i

According to my invention the cross bars whichsupport the illerbrick aremade integral with head or end portions which cooperate with adjoiningmembers to prevent displacement when in proper position. .One form of.my filler brick supporting member is illustrated in Figures 1 to. 5,inclusive, and

Vdesignated 12. The supporting member vv12' comprises a cross bar 13which is diagonally disposed with respect to the flow passage thereaboveand is preferably rigidly united with head portions 14. Thus thesupportingA member as a whole is substantially H- haped in section. Eachofthe-head portions 1,4V

above. The manner of associating the individual supporting member 12 isclearly illustrated in Figure 1, in which the cross bar members 13extend in directions parallel with e'each other. In this form it will beapparent that each checker brick seats upon tive adj oining supportingmembers, or, in other words, upon the two heads of one supporting memberand portions of the heads of four adjoining If desirable a lug 15 may beformed integral with the cross bar 13 and extend in an upward directionto cooperate with filler brick 16 supported thereabove and to enableproper positioning of the checker brick. An additional lug 17 may extendfrom the bot-tom of the cross bar corresponding to the upper lug 15 andserve to properly position and hold the supporting members in place. Thesupporting members may directly rest upon octagonal tile, vor brickmembers 18, which, in turn, rest upon the rider tile members 11 or thesupporting members may rest directly on the rider tile 11 themselves.

The supporting members may be constructed entirely of cast metal or thecross bar alone may be of metal integrally cast with brick head portionsor the entire support may be formed of brick.

Figure 6 illustrates a modification of my invention when ordinaryblock-shaped checker brick is employed. The supporting member 20 isshown in this form to extend entirely across the checker chamber and maybe described as three Z-members integrally united. Thus thermember 20includes diagonal cross bars 21, metal cross braces 22 and end portions23. The diagonal members 21 support the liller brick thereabove and theportions 22 and 23 rest upon the rider tile and carry the checker bric VY Therefore, in both forms ofmy invention the supporting members aresoformed that the flow of gas isV unrestricted and displacement of thesupporting members cannot occur. A l

Various modilications may be resorted to without departing fromthespirit of my invention as expressed in the appended claims.

In checker work construction, a plurality of octagonal shaped checkerbrick arranged in vertical columns and forming a plurality of verticalflow passages, filler brick loosely inserted diagonally of k the flowpassages and supporting members comprising head portions united by anintegral cross bar whereby the head portions serve as supports for theVchecker brick and the cross bar portions serve as supports for theillerbrick.

f 2. A supporting member for checker brick and filler brick comprising across baradapted to be positioned diagonally of the ilowpassage througha column of checker brick for supporting filler brick therein and headportions integral with the ends of said cross bar adapted to cooperatewith the head portions of additional supporting members to form asubstantially level base for supporting co1- umns of checker brick.

3. In checker work construction a plurality of hollow checker brickadapted to-be superposed in layers to form vertical flow passages,filler brick loosely inserted diagonally of the flow passages and aplurality 'of supporting members disposed in a layer
